I suspect this may be a browser/platform issue. I've recently run some tests and below are the most interesting results (mime types):
IE 6 on PC: something.jpg -> image/pjpeg something.tif (pc format) -> application/octet-stream something.tif (mac format) -> image/tiff IE 5 on Mac: something.bmp -> application/octet-stream something.jpg -> image/jpeg NS 4.7 on Mac: something.bmp -> image/x-MS-bmp Opera 7 on PC: something.bmp -> image/x-windows-bmp I suspect if you want to validate jpgs, use image/jpeg and image/pjpeg or validate by examining the extention (ie ".jpg"). I don't know how safe the latter is. HTH, m > -----Original Message----- > From: John T.
